Pennsylvania's 20 electoral votes seem up for grabs in a new Siena Research Institute Poll that shows a tight race, with President Obama leading Republican Mitt Romney 43 percent to 40 percent.

The Siena College survey finds 12 percnet of the state's voters undecided. It shows Romeny winning in the Philadelphia suburbs. "With a month and two more debates to go, Pennsylvania's direction on the road to the White House remains in doubt," said Don Levy, the poll director.

Obama is viewed favorably by 49 percent of the voters, to 44 percent who view the president unfavorably, while Romney's ratio is 40 percent favorable to 49 percent unfavorable, the poll finds.

Results are based on interviews with 545 likely voters between Oct. 1 and Oct. 5, and results are subject to a margin of error of plus or minus 4.2 percentage points.
